Abstract (en)
[origin: WO2006103375A2] The invention relates to thermally-stable mineral wool which can dissolve in a physiological medium, comprising fibres containing the following constituents, expressed in percentage by weight, namely: 35-60 % SiO<SUB>2</SUB>, preferably 39-55 %; 12-27 % Al<SUB>2</SUB>O<SUB>3</SUB>, preferably 16-25 %; 0-35 % CaO, preferably 3-25 %; 0-30 % MgO, preferably 0-15 %; 0-17 % Na<SUB>2</SUB>O, preferably 6-12 %; 0-17 % K<SUB>2</SUB>O, preferably 3-12 %; 10-17 % R<SUB>2</SUB>O ( Na<SUB>2</SUB>O + K<SUB>2</SUB>O), preferably 12-17 %; 0-5 % P<SUB>2</SUB>O<SUB>5</SUB>, preferably 0-2 %; 0-20 % Fe<SUB>2</SUB>O<SUB>3</SUB>; 0-8 % B<SUB>2</SUB>O<SUB>3</SUB>, preferably 0-4 %; and 0-3 % TiO<SUB>2</SUB>, and at least one phosphorous compound that can react with said fibres at a temperature of less than 1000 °C in order to form a coating on the surface thereof. The invention is characterised in that the phosphorous content of said compound, as expressed in phosphorus atom weight, varies between 0.0005 %, in particular more than 0.01 %, and 1 %, in particular less than 0.5 %, of the total weight of the fibres. The invention is also characterised in that a phosphorus compound is a molecule in which the phosphorus atom(s) are bound to at least one carbon atom either directly or by means of an oxygen atom.
